【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、高層住宅等における軽量間仕切り壁に関
し、遮音性と耐火性の向上を図ったものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a light-weight partition wall in a high-rise house or the like, and aims at improving sound insulation and fire resistance.
近年、高層住宅等において構築される軽量間仕切り壁
には、例えば第６図に示すように、千鳥状に配した独立
木造下地の両面に同種の石膏ボードを２枚重ね、その空
間にロックウールまたはグラスウール等の吸音材を挿入
した２重壁構造のものがある。In recent years, as shown in FIG. 6, for example, as shown in FIG. 6, two gypsum boards of the same type are stacked on both sides of a staggered independent wooden base, and a rock wool or There is a double wall structure in which a sound absorbing material such as glass wool is inserted.
しかしながら、上気従来の軽量間仕切り壁において

損失の欠損があるため、建設大臣が定める遮音基準に合
格する壁にするには必要以上に石膏ボードの厚みや重
量、吸音材及び壁の厚み等を増さなければならない問題
があった。However, in the conventional lightweight partition wall, the wall itself has a predetermined fire resistance, but as a defect that the double wall generally has, there is a loss of sound transmission loss due to the coincidence effect. In order to obtain a wall that passes, there is a problem that the thickness and weight of the gypsum board, the thickness of the sound absorbing material, the thickness of the wall, and the like must be increased more than necessary.
本発明は、上気従来構造による軽量間仕切り壁の問題
点を解決するために為されたもので、間仕切り壁の厚み
等を増すことなく、音響透過損失の欠損のない遮音性、
耐火性に優れた間仕切り壁を提供することを目的とする
ものである。The present invention has been made in order to solve the problem of the lightweight partition wall with the conventional structure, without increasing the thickness and the like of the partition wall, sound insulation without loss of sound transmission loss,
It is an object of the present invention to provide a partition wall having excellent fire resistance.

見に基づいてなされたのである。In the present invention, a panel constituting a wall surface is composed of two types of gypsum boards, and a specific ratio between a surface density of a gypsum board for overlay located outside the wall and a surface density of a gypsum board constituting the inside of the wall is specified. This is based on the finding that the above problem can be effectively solved.

ードリブを千鳥状に対向させて配設して成ることを特徴
とする遮音間仕切り壁を提供する。That is, the present invention provides, in the structure of the lightweight partition wall mainly composed of gypsum board, plasterboard ribs are provided along both longitudinal edges of one of the front and back surfaces of the gypsum board, and between the two ribs. The panel on which the sound absorbing material is laminated is placed so that the surface of the panel on which the ribs are provided is on the inside, and both edges in the short direction of the panel face the upper and lower runners between the upper and lower runners. The surface density of the gypsum board forming the panel is formed on the surface of the base wall formed by connecting a plurality of panels sequentially so that the edges in the longitudinal direction of the panels are in contact with each other so that the direction is the vertical direction. 1: 0.1 ratio
A gypsum board for upholstery in the range of ~ 1: 0.9 is fixed to form one wall body, and on the opposite side, a similar structure to the wall body is adhered to the wall body via a space or panel. A sound insulation partition wall, wherein the gypsum board ribs are arranged in a staggered manner.

膏ボードを積層することによる遮音効果と相埃って、コ
インシデンス効果による音響透過損失の欠損のない遮音
性、及び耐火性の優れた間仕切り壁となる。According to the configuration of the partition wall of the present invention, since the gypsum board ribs having an appropriate width for reinforcement are arranged in a staggered manner on the opposing surface of the boundary wall, the rigidity is increased and the bending strength is excellent. Because it can be a structure that does not require studs,
In addition, the gypsum board ribs partially change the surface density of the panel, and further, since the gypsum board ribs are arranged to face each other in a staggered manner, the partial surface density of the entire wall also changes. Sound insulation with no sound transmission loss due to coincidence effect due to the sound insulation effect and the dust by laminating the gypsum board that constitutes the panel and the gypsum board with different areal density with the intervening sound absorbing material and air layer between And a partition wall having excellent fire resistance.
尚、ここで用いる石膏ボードとは、石膏を主体とする
芯材そのものであってもよく、これを石膏ボード用原紙
で被覆したものであって、例えばJISA6901,A6911,A691
2,A6913等に定められる石膏ボードが挙げられる。Incidentally, the gypsum board used here may be a gypsum-based core material itself, which is coated with a gypsum board base paper, for example, JISA6901, A6911, A691
2, gypsum boards specified in A6913 and the like.
更に、パネルに設ける石膏ボードリブの適切な幅（ｗ
mm）は、次の不等式 ｔ＋ａ≦ｗ＜1/4W t:パネルを構成する石膏ボードの厚さ（mm） W:パネルの幅 （mm） a:定数10 （mm） を満足するのがよい。Furthermore, the appropriate width (w
mm) satisfies the following inequality: t + a ≦ w <1 / 4W t: thickness of gypsum board forming panel (mm) W: width of panel (mm) a: constant 10 (mm)
尚、石膏ボードリブ幅を特定寸法とする理由はパネル

た寸法に満たない場合、又は石膏ボードリブ幅がパネル
幅の1/4以上の寸法である場合は、コインシデンス効果
による音響透過損失の欠損防止にさほど寄与しないから
である。In addition, the reason why the gypsum board rib width is set to the specific size is also meaning to strengthen the panel, but to partially change the surface density of the panel and to more effectively eliminate the loss of sound transmission loss due to the coincidence effect, If the gypsum board rib width is less than the dimension of the gypsum board constituting the panel plus 10 mm, or if the gypsum board rib width is 1/4 or more of the panel width, sound transmission loss due to the coincidence effect This is because it does not significantly contribute to the prevention of loss.

石膏ボードリブと比べ側面が石膏ボード用原紙で被覆さ
れ、より強化される利点がある。As disclosed in Japanese Utility Model Publication No. 54-21854, a gypsum board rib is provided with a margin for forming the rib from the edge along a longitudinal edge of one of the front and back surfaces of the gypsum board. The two cut V-grooves (Fig. 3) that have been cut off may be bent to the V-groove side and bonded and laminated (Fig. 4). Can be stacked together with glue or glue nails (Fig. 5)
May be. The gypsum board rib of FIG. 4 has an advantage that the side face is covered with a gypsum board base paper and is more reinforced than the gypsum board rib of FIG.
石膏ボードリブの長さはパネルの長さと同じでもよ
く、また天井や床に設けられるランナーのフランジの高
さ分を各々差し引いた長さでもよい。The length of the gypsum board rib may be the same as the length of the panel, or may be a length obtained by subtracting the height of the runner flange provided on the ceiling or floor.
吸音材としては、一般にグラスウール、ロックウール
等の無機繊維マットを使用出来る。In general, an inorganic fiber mat such as glass wool and rock wool can be used as the sound absorbing material.
隣接するパネルとパネルの連結方法は、単に突き付け
たり、また接着剤等を用いて行なってもよく、互いに接
触していればその方法は特に限定されない。The method of connecting the adjacent panels may be simply abutting or using an adhesive or the like, and the method is not particularly limited as long as they are in contact with each other.

特に肝要である。Further, the surface density of the gypsum board fixed to the ground wall surface formed by connecting the panel between the upper and lower runners is smaller than the surface density of the gypsum board constituting the panel, and the ratio is 1: 0.
Use the one in the range of 1-1: 0.9. The reason is that otherwise, it does not significantly contribute to preventing loss of sound transmission loss due to the coincidence effect. It should be noted that, when the gypsum board is fixed to the base wall surface, the position of the joint is shifted from the joint of the base wall to laminate the gypsum board.
Especially important.
上記パネルを構成する石膏ボードとしては一般的に面
密度が4.5〜25kg/m2のものが使用される。Generally, gypsum boards having a surface density of 4.5 to 25 kg / m 2 are used as the gypsum boards constituting the panels.

仕切り壁。In a structure of a light-weight partition wall mainly composed of a gypsum board, gypsum board ribs are provided along both longitudinal edges of one of the front and back surfaces of the gypsum board, and sound is absorbed between the ribs. The panel in which the materials are laminated is arranged such that the surface provided with the ribs of the panel is on the inner side, and between the upper and lower runners, both edges in the short direction of the panel face the upper and lower runners,
Gypsum board forming the panels on the surface of a base wall formed by connecting a plurality of panels sequentially so that the longitudinal edges of the panels are in contact with each other so that the longitudinal direction of the panels is vertical. A surface gypsum board having a surface density ratio of 1: 0.1 to 1: 0.9 is fixed to form one wall body, and on the other side, the wall body is in close contact with or via a space. A sound-insulating partition wall, wherein a structure similar to the wall is disposed with the gypsum board ribs of panels facing each other in a staggered manner.
